Good that you found out that field names are not required to be unique.
I did not catch this when I wrote emms-info-native.  According to the
spec it is even encouraged:

  "Field names are not required to be unique (occur once) within a comment =
header. As an example, assume a track was recorded by three well know artis=
ts; the following is permissible, and encouraged:
=20=20
  1ARTIST=3DDizzy Gillespie
  2ARTIST=3DSonny Rollins
  3ARTIST=3DSonny Stitt"

(from https://xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-820005)

But why defcustom?  Why not support multiple values for any field?  The
spec does not restrict that, and in my opinion we should not either.
